FUETEE OLGF A. ENSTROM ANTD ADOLF E. DAHLIN, OF LYNN, MASSACHUSETTS, ASSIGNOBS TO MAXVJELL EDELMAN, 015 BOSTON, MASSACHUSETTS.

PRINTER S QU'OIN.

Application filed December 14, 1922. Serial No. 606,949.

To aZZ whom it may concern:

Be it known that we, OLOF A. ENSTROM and AnoLr E. DAHLIN, respectively a subject of the King of Sweden and a citizen of the United States of America, and residents of Lynn, in the county of Essex and State of Massachusetts, have invented certain new and useful Improvements in Printers Quoins, of which the following is a specification.

This invention relates to quoins for use in type-setting, and has for its object the provision of a device of this character which may be adjusted readily, and in which the two parts of the body thereof will move in a straight line toward and from each other during such adjustment.

The invention consists of a body portion made in two parts, one of which is provided with a flange positioned in a groove in the other part, said flange having an inclined wall with which the end of a threaded member in the grooved part coacts'to separate the two parts as desired.

The invention further consists in resilient means for normally retaining the two parts in contact.

The invention further consists in certain novel features of construction and arrangement of parts which will be understood readily by reference to the description of the drawings and to the claims to be hereinafter given.

For the purpose of illustrating the invention, one preferred form thereof is shown in the drawings, this form having been found to give satisfactory and reliable results, although it is to be understood that the various instrumentalities of which the invention consists can be variously arranged and organized, and that the invention is not limited to the precise arrangement and organization of the instrumentalities as herein shown and described, except as required by he scope of the appended claims.

' Of the drawings:

Figure 1 represents a plan of a quoin embodying the principles of the present invention.

Figure 2 represents an elevation of the same.

Figure 3 represents an elevation of one part of the body of the quoin.

Figure 4; represents an elevation of the other part of said body.

Figure 5 represents a transverse section of same on line 5, 5 on Fig. 1, and

Figure 6 represents a transverse section of same on line 6, 6 on Fig. 2.

Similar characters indicate like parts throughout the several figures of the draw- Tn the drawings, 10 is the main part of a quoin and has formed in one side thereof a longitudinal groove 11 extending from end to end thereof. The other part 12 of the body of the quoin is provided with a flange 13 extending from end to end'thereof, and positioned in the longitudinal groove 11.

Centrally disposed on the flange 13 is an inclined portion 14; with which 'coacts the rounded end 15 of a threaded member 16, adjustably mounted in the main part 10 of the quoin. This threaded member 16 is provided in its upper end with a flat-sided socket 17 adapted to receive a key, by which the threaded member may be rotated about its axis to move its rounded end 15 against the inclined portion 1 1 of the flange 13.

When this rounded end 15 is forced into contact with the inclined portion 14, the part 12 will be forced outwardly from the part 10, separating the two parts 10 and 12 to any desired degree.

In the main part 10 are riveted two studs 18 near the ends of said. part 10, these studs being provided with heads 19 on their outer ends. The heads 19 are positioned within cylindrical depressions 20 formed in the movable part 12, and the bottom of said depressions 20 form shoulders 21 against which bear one end of helical springs 22, the opposite ends of which bear against the heads 19.

The resiliency of these springs 22 tend to retain the two parts 10 and 12 in contact under all normal conditions, and when the two parts are adjusted relatively to each other, said springs will tend to retain the inclined portion 11 of the flange 13 in contact with the rounded end 15 of the threaded member 16.

' The diameter of the heads 19 is slightly less than the diameter of the depressions 20, and in a similar manner the diameter of the shanks of the studs -18 is slightly less than the shouldered portions 21.

This provides a means whereby the movable part 12 may readily adjust itself relatively t0 the main part 10, should there be, for any reason necessity for such adjustment in locking the type form into the chase. s

This makes a simple and very effective quoin for printers use which is economically constructed. One particular advan-v Having'thus described our invention, we

claim:

1. A quoin, the body portion of which is formed in two parts, one of which has a horizontal flange positioned in a groove in the other part extending from end to end thereof, which part is provided with adjustable means coacting with said flange for separating vthe parts.

2. A quoin, the body of which is formed in two parts, one of which has a horizontal flange having an inclined portion positioned in a groove in the other part, which part is provided with adjustable means perpendicular to the upper face of said flange and provided with an inner end c0- acting with the inclined portion of said flange for separating the parts.

8 A quoin, the body portion of which is formed in two parts, one of which has a flange with an inclined portion positioned in a groove in the other part; and a threaded member in said other part having a rounded end coacting with the inclined portion of said flange. I

4:. A quoin, the body of which is formed in two parts, one of Which has a flange positioned in a groovein the other part, which part is provided with adjustable means coacting with said flange for separating the rts; and resilient means for forcing the two parts toward each other.

5. A quoin, tie body of which is formed in two parts, one of which has a flange provided with an inclined portion, positioned in a groove in the other part, which part is provided with adjustable means coacti'ng with the inclined portion of said flange for separating the parts; two headed studs secured'to one part with the heads in deprese sions in the other part; and springs surrmniding said pins between the heads thereof and the bottoms of said depressions.
